3 Claims.

. The invention relates to roundabouts, particularly adapted to be attached to a vertical column, for instance in the basement of a house, and applied thereto without modifying the construction of the column.

A further object is to provide a roundabout adapted to be attached to a vertical column, and comprising a separable clamp clamped to the column, and a rotatable separable member encircling the column above the clamp and adapted to rotate on the clamp. Also to provide outwardly extending arms carried by the separable member above the clamp and terminating in seats for children. The outwardly extending members are vertically adjustable in relation to the floor.

With the above and other objects in view the invention resides ,in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Figure 1 is a view in elevation of the roundabout attached to the column.

Figure 2 is a horizontal sectional view taken on line 22 of Figure 1.

Figure 3 is a horizontal sectional View taken on line 33 of Figure 1.

Figure 4 is a view similar to Figure 3, but showing the clamp formed to be attached to a column rectangularly shaped in cross section;

Figure 5 is a view similar to Figure 3, but showing a clamp shaped to be attached to an I-beam.

Figure 6 is a view similar to Figure 1 showing a modified collar support.

Figure 7 is a perspective view of the collar support.

Figure 8 is a modified form of roundabout of a portable type.

Figure 9 is a horizontal sectional view taken on line 99 of Figure 8.

Referring to the drawing, the numeral I designates a round vertical column, of the type used in the basements of houses for supporting beams above the concrete floor 2.

Extending around the column I is a clamp 4 formed from segmental sections 5, the ends of which sections terminate in flanges 6, which flanges are clamped together by bolts 1. It will be seen that the clamp can be rigidly positioned and held against downward displacement on the column I. The upper sides of the sections 5 are provided with ball raceways 8, in which antifrictional bearings 9 are disposed.

Encircling the column I, above the clamp 4 is a rotatable member [0, formed from sections II. It will be noted that the sections I I, forming the clamp, are slightly out of engagement with the periphery of the column I. The ends of the sections 1 l terminate in flanges l2 and clamped between the flanges IZ, by means of bolts I3, are radial spring arms l4. Disposed on the outer ends of the arms [4 are seats l5, as shown in Figure 1, adapted to be occupied by children operating the device. Pivotally connected on outwardly extending arms 16, carried by the sections H, at H, are outwardly and downwardly extending spring arms l8 having the seats 15 thereon. The spring arms [8 may be adjusted upwardly or downwardly by adjusting the bolts H), which bolts are threaded through the arms It, clearly shown in Figure 1. By providing this adjustment the seats can be adjusted upwardly or downwardly in relation to the concrete floor, and according to the length of the legs of the occupants of the seats. In operation, there can be an up and down springing movement, incident to the flexing of the arms [8 and I4, and when the roundabout movement is desired, the occupants can set up the rotary movement by engaging their feet with the floor 2, hence it will be seen that the roundabout may be applied to a column in a basement so that children can play in the basement.

Referring to Figure 4, wherein a different shaped clamping member 4 is provided, the operation is the same except each section 5 is provided with an angular recess 20 for the reception of a concrete column 2 I, rectangular in horizontal cross section. In this form additional securing means is provided in the form of set screws 22.

Referring to Figure 5 the clamp sections 4 are substantially the same in operation as in Figures 2 and 3, however the inner sides of the sections 5 are shaped to form flanges 23, and recesses 24, for the reception of the flanges 25 of a vertical I-beam 26. I-beams are sometimes used in basements.

From the above it will be seen that a roundabout is provided which is simple in construction, can be applied to a basement column or other vertical support, and the seat carrying arms may be adjusted upwardly or downwardly. An antifrictional bearing arrangement is provided, however this may be eliminated if desired.

Referring to Figures 6 and '7 wherein a modified form is shown, the anti-frictional bearings are eliminated, and the member 10 comprising sections l I rests on the upper side of a clamping collar 21, clamped around the post I. Clamping collar 2'! is formed from segmental sections 28, the ends being provided with eyes for the reception of securing bolts or pins 29 which hold the sections 28 in tight frictional engagement with th p 1. ot erw s h at on, is the same as in the other forms.

In Figures 8 and 9 is shown a portable device which may be stored when not in use, and in this form the roundabout is supported on a base 30, which base has secured thereto a short post Ia, by bolts 3 I. The short post la is braced by downwardly and outwardly extending brace arms 3-2 which have their lower ends anchored, to the base 30 by means of lag screws or bolts 33. Rotatably mounted on the upper end of the post la is an inverted chambered member 34, which member 34 is provided with radial seat supporting arms 18a. The device is operated by children on seats at the outer ends of the arms Ia, and rotate the device with their feet engaging the floor.

The invention having been set forth what is claimed as new and useful is:

1. A roundabout comprising a support memher, a ring rotatably mounted on said support member having outwardly. extending arms, spring arms having their inner ends disposed in overlying relation to the arms of said ring and hingedly connected to the upper sides thereof and adjusting screws extendingthrough the outwardly extending arms of said ring and engaging the spring arms on their under sides adjacent the hinging points of the spring arms.

2. A roundabout comprising a support member, a ring rotatably mounted on said support member, a seat carrying spring arm having its inner end hingedly mounted on the upper side of said ring, and an adjusting screw carried by said ring engaging the under side of said spring @l QH'QWWQLX ilf hingilig 12 1111; whereby the spring arm may be adjusted upwardly or downwardly.

3. A roundabout comprising a support member, a ring rotatably mounted on said support member having laterally extending arms, spring arms having their inner ends hingedly connected to the upper sides of said arms inwardly from the outer ends of the. arms, seats carried by the outer free ends or said spring arms, and adjusting screws threaded through the outer ends of the laterally extending arms and engaging the under side of said spring arms at a point outwardly spaced from the. hinged inner ends of' said spring arms, said adjusting screws forming means whereby the outer ends of said spring arms may be adjusted: upwardly and downwardly.
